I have had an issue I have not seen here before. My Roamio just decided it wouldn't accept remote commands. I use a Harmony and thought it might be that so I dug up the OEM remote and it still wouldn't accept a command. None. I think I pushed all of the buttons. After a reboot everything went back to normal and has worked fine for the last day or so.

Is this common? This is my first Tivo so I am not sure if this happens a lot.

Had this happen on my Elite the other night. I was setting it up for my wife so I was transferring a bunch of shows. I switched over to check on it and it would not respond. It was still transferring so I left it alone. The next morning I tried again and it still would not respond but the transfers all completed. I tried to do the trick where you hold down the format button to reboot and that didn't work either, so I finally pulled the plug. After that it worked fine.

It wasn't even connected to cable or a TA yet, so that couldn't have been the problem.

Has happened 6 times now on my Roamio Pro. I left it overnight to see if it would recover. No dice. Reboot cleared it up. This is getting old. It just seems to happen out of the blue. This time, I went to hit pause and the thing was deaf to the remote. Lights blink, but nobody home.

Haven't had this happen on Roamio but had it happen with my Elite probably once every 3 months. If you have the iOS/Android app installed, you can use that to flush out whatever the problem is. I usually would bring up My Shows on the iOS app and initiate playback of a recorded show on TV. After that the physical remote would work fine. Much faster than a reboot. Hitting the TiVo button on the virtual remote may also bring the physical remote back to life. So just try 2 or 3 commands related to changing the current "state" (ie from show A to show B...or from Live TV to a recorded program...or from Live TV to TiVo Central, etc) of the TiVo in the iOS/Android app...usually 1 of them will end up fixing the physical remote problems.
